I use Windows Firewall with Advanced Settings and I don't know enable connection for PortableApps browsers.

I use task manager to find the exe browser (FirefoxPortable/App/Firefox64/firefox.exe, OperaPortable/App/Opera/46.0.2597.32/opera.exe or K-MeleonPortable/App/K-Meleon/k-meleon.exe) and I create a rule to allow this exe to connect to HPPT & HTTPS (TCP 80 & 443) like a resident browser. But it can't connect.

I think that PortableApps browers use a Windows service to connect, but which one ?

How can I do to allow PortableApps browers to access internet without a general rule to allow TCP ports 80 & 443 ?

Make sure that the rules you create are ones that allow, not block/disallow. Usually Windows will ask if you would like to add a new rule if it thinks the app needs it (unless this has been turned off by an administrator)

Delete the rules you made and try using your PortableApps browsers. They will either work or you'll get a firewall prompt. If they just don't work and there is no prompt, an administrator has turned the prompt off.

This is the same rule that I use for resident browsers. The difference is that portable browsers are still blocked by the firewall.

A solution that isn't no one is to create a rule to open ports TCP 80 and 443. But the problem is that rule isn't selective, it applies to all apps.

I restore default parameter in Windows Firewall and I create a rule for Firefox x64 installed and FirefoxPortable (/App/Firefox64/Firefox.exe), but only the portable browser is blocked. But I'm not this problem in my VMs (Win 7 & Win 10).

Does the portable app installed in a drive that doesn't exist when you boot up your pc? for example in a Truecrypt/Veracrypt container (later mounted as a drive) or it's inside an usb drive which is not mounted when pc is booted up.

I found out that Windows Firewall skips rule with 'invalid program' (program that's not there when Windows Firewall started).

I also just found out a simple (and kinda stupid) trick to make Windows Firewall re-load rules..turn Windows Firewall Off, then On (do this after you've mounted the drive or plug in the usb drive).

I find the problem. In my VMs I put apps in C:\App, but in my PC I put them in the user directory.
The problem is %USERPROFILE% in the path of the exe in the rule.
The solution is to type the full path.
